Abstract
The apparatus of the present invention comprises a compliant structure for use in reducing bending stress at the ends of an elongated cylindrical tether which may, for example, be used to connect a floating platform supported by a body of water to the floor thereof. The apparatus comprises a plurality of tubular support members concentrically arranged about the elongated cylindrical tether at the tether's end connection. Each tubular support member is connected to each adjacent tubular support member in a manner that allows the entire assembly of tubular members to deflect in unison as the cylindrical tether deflects.
